period

So unfortunately this isn't my month atkeast I don't think so. I'm supposed to get my period tomorrow and I'm starting to cramp and a hint of color when I wipe now. But last month . I spotted a week before I was supposed to get my period and that's all that I had last month was that scouple hours of spotting . So I'm just confused . I hope this month I actually will bleed . But even when I do. It's only for 2 days?? Does anyone else's period like this?? I've always been 2 days.
